A doorknob is a very unique form of lever consisting of a wheel [and naturally a wheel has an axle]. In actuality a wheel IS a battery of an infinite number of levers!
Some common questions about simple machines include: How do simple machines make work easier? What are the different types of simple machines? How do simple machines affect force and distance in work? How can simple machines be combined to create complex machines?
All simple machines change the direction or magnitude of a force to make work easier. They operate on a basic mechanical principle and do not have moving parts. Simple machines can be combined to create more complex machines.
You are using a wheel and axle simple machine when you twist a doorknob. The wheel (the doorknob) rotates on the axle (the spindle), allowing you to easily open or close the door.
No, a doorknob is an example of a Wheel & Axle.
A CATAPULT IS A LEVER!!!
Simple machines cannot create energy; they only change the direction or magnitude of a force. Additionally, they cannot violate the law of conservation of energy, meaning they cannot create more energy than they receive.
No, touching a metal doorknob will not create a spark under normal circumstances. Sparks are produced when there is a sudden release of energy, typically from friction or static electricity buildup. Touching a metal doorknob does not generate sufficient energy to create a spark.

Simple Machines was created in 1990.
Simple Machines ended in 1998.
The similarities are that simple and complex machines are both made up of simple machines
